UR-Nexus 1.65.10

• Reworked approved-plan execution into a capability-aware task graph. Plans
  now split separately completable outcomes, keep genuinely atomic work whole,
  express review-to-fix and verification dependencies, and launch only ready,
  non-conflicting work in parallel waves of at most eight. The handoff uses
  TaskCreate/TaskUpdate, TodoWrite, or the numbered plan according to the
  tools actually available, and never advertises a worker that is not active.
• Made the built-in Explore and Plan agents available in the standard CLI with
  structurally read-only tools. Parent and child execution boundaries reject
  mutations even after permission-hook rewrites, custom agents cannot inherit
  the exemption by reusing a name, and team creation/deletion rechecks live
  plan mode before changing state.
• Task tools now accept positive safe-integer JSON task IDs as well as strings
  and normalize them to canonical persisted strings, fixing smaller models
  that call TaskUpdate with taskId: 1.
• Exact edit failures now return a bounded preview and a verified line anchor
  for a fresh, smaller contiguous match. Large cross-section replacements fail
  closed with actionable recovery instead of retrying unchanged or applying a
  risky fuzzy edit.
